Fiber optic identifiers typically possess the following basic functions:
Signal Direction Identification: Clearly displays the transmission direction of the optical signal within the fiber using left and right LED indicators.
Relative Power Indication: Intuitively displays the relative intensity of the optical signal via a digital display tube or on-screen numerical readout.
Frequency Tone Identification: Effectively identifies common modulated signals (270 Hz, 1 kHz, 2 kHz) and provides alerts—either through an audible buzzer or indicator lights—to facilitate fiber tracing.
Non-destructive Testing: Features a specially designed fixture that ensures no damage is inflicted upon the optical fiber during testing.
